tically and laterally, thus to be adapted for use in connection with a door that sags or warps. Doors, particularly new ones, often become distorted or slightly displaced until the parts have become thoroughly seasoned, with the result that it very often becomes necessary to remove the strike plate to adjust it to another position in order to enable the latch 01' bolt of the lock to become' properly seated within the strike plate. This readjustment of the strike plate has often resulted in mutilation of the door jamb or casing.

'- One of the objects of the present invention is to provide a strike plate which is adjustably mounted so that it can be moved to any desired position without causing mutilation of the door jamb;

A further object is to provide a structure of this character which is simple in construction, cheap to manufacture, and which can-be applied as readily as an ordinary strike plate.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in thecombination andarrangement ofparts' and in the details of construction hereinafter described and claimed, it being understood that ch anges'in the precise embodiment of the invention herein disclosed, can be made within the scope of what is claimed, without departing fromthe spirit of the invertv tion. In the. accompanying drawings the preferred 7 form of the invention has been shown.

In said drawings: Figure 1 is a front ele-. vation of a strike plate embodying the present improvements. Fig. 2 is a vertical section therethrough on the line A-B Fig. 1. Fig. 3 is a rear elevation of the main member of the strike plate. Fig. 4; is a front view of the adjustable member.

have invented a Referring to the figures by characters of reference C designates a portion of a door amb having the usual mortise M and bolt receiving recess R. The strike plate constrtuting the present invention is designed to be secured in the mortise M and to extend over the recess R. This strike plate is made up of two members. The main plate 1.is provided with spaced angular openings 2 and 3 for the reception ofthe latch and bolt respectively of the lock, there being a tongue at extending from the plate and opposite the latch' receiving opening 2. Upon its outwardly exposed surface, when the said plate or member 1 has been inserted in its position in the mortise M, is a suitable retaining or clamping means, preferably in the form of serrations, as 5, and located near the end-portions of the said plate or menibcr, these serrated portions being provided with openings 6 which'can be rectangular as shown or of any other desired shape.

Ilate 1, as has been stated, is adapted to be fitted within the mortise M' but is both I shorter and narrower than the mortise so as thus to be capable of shifting longitudinally and laterally therein. A holding plate 7 is adapted to fit snugly within the mortise M and to extend throughout the len h andwidth thereof. Upon its inner sur ace-portions, adjacent to and bearing upon the out wardly exposed surface-portions of the plate or member 1, the said holding plate 7 is also provided with a suitable retaining or clamping means, also in the form of serrations as 8, while the intermediate portion is cut away, leaving a narrow strip .9 adapted to overlie that portion of the plate 1 remote from the tongue 4. Openings 10 are formed in the end portions or the plate 7 and are adapted to receive fastening screws 11 or the like, these fastening devices ex-- tending through the openings 6 and into the jamb C. When the parts are first as-- sembled the plate 1 is shifted vertically or laterally so as to bring the openings 2. and 3 into proper positions relative to the latch and bolt of the lock on the door to be secured. After the plate 1 has been properly adjusted, plate '2' is clamped thereagainst by means of the tastening screws 11, theserrations 8 engaging the serrations 5 so as to prevent the plate 1 frompulling laterally out of the mortise M. The pressure of the plate 7 against ,theplate 1 is suficient to hold said plate 1 against vertical displacement.

It will be seen that a device such as herein described can be cheaply manufactured, can be applied as readily as an ordinary strike plate, and is advantageous for the reason that it can be quickly and readily adjusted so as to properly receive the latch and bolt of a lock. Furthermore, the inner surface-portion of the plate or member 1 being smooth, there are no projections or serrations to bite into the Wood which, as will be evident, soon mars and destroys the usefulness of the surface-portion'ofthe mortise, as will-be clearly evident.

What is claimed is 1. A strike-plate for door locks comprising an inner main keeper-section and an outer holding plate, the said main keepersection being provided with spaced angular openings for reception of the latch and bolt of a lock, and a tongue extending laterally from one of the marginal edges, opposite one of said openings, said tongue serving cated betweenand upon the immediate con-- tacting surfaces of the said keeper-section and the said holding plate.

2. A strike-plate for door locks comprising an inner main keeper-section formed with enlarged screw-receiving openings, the said main keeper-section being provided with spaced angular openings for reception of the latch and bolt of a lock, and a tongue extending laterally from one of the marginal edges, opposite one of said openings,

said tongue serving as a finger-piece for adjustment of said main keeper-section, said keeper-section being slidably fitted both longitudinally and laterallywithin the mor smooth surface to prevent marring of the wood, and an outer holding plate adapted to be snugly fitted within said mortise, the said holding plate being formed with screwreceiving openings, retaining screws in said last-mentioned openings, said screws extending into and through the enlarged openings in the said main keeper plate and screwed into the door-jamb, retaining serrations upon the said main keeper-section and retaining serrations upon the said holding plate, the said serrations being located between and upon the immediate contacting surfaces of the said keeper-section and the said holding plate.

3, A strike plate including a main plate having a bolt receiving opening, a laterally extending tongue serving as a finger-piece for adjustment of said plate, and serrated end portions, each of said serrated end portions containing a relatively large fastener receiving opening and having a rear smooth surface to prevent marring of the wood when inserted in the mortise of a door jamb, a holding plate having its end portions serrated for engaging the serrations on the end portions of the main plate, there being relatively small fastener receiving openings within the serrated end portions of the holding plate, the middle portion of the holding plate being cut away to expose the bolt receiving opening in the main plate, and fastening means fitting snugly within the openthrough the end openings in the main plate ings in the holding plate and extendinisfi to hold the serrations, upon the two plates in engagement with each other, said main plate being adjustable laterally relative to the holding plate when the serrations are disengaged and longitudinally of the holding plate when the pressure of the holding plate upon the main plate is reduced.
